Apoptotic effect of Pseudomonas aeruginosa exotoxin A in human tongue squamous cell carcinoma(SCC) 25 cells

Pseudomonas aeruginosa exotoxin: effect on cell cultures.

The Immunomodulatory Effect of Recombinant Exotoxin A of Pseudomonas Aeruginosa on Dendritic Cells Extracted from Mice Spleen

 Background & Objective: Dendritic cell (DC) is as a key cell in activation of immune response against microbes and disease. Therefore, the effect of recombinant exotoxin A of Pseudomonas aeruginosa on the maturity and the activation of DCs was evaluated in this study. Materials & Methods: Recombinant exotoxin A was produced from Pseudomonas aeruginosa DNA. MTT assay was used to evaluate ...

Tongue Squamous Cell Carcinoma: A Clinical Study

  Background and Objectives: Squamous cell carcinoma of the tongue (SCCOT) is the most common malignant neoplasm in oral cavity. At the time of the diagnosis of SCCOT regional metastases with a high mortality rate are common, which is due to the extensive lymphatic system drainage of the tongue. Although the level of healthcare has significantly improved, the survival rate is still low with an...

The Prevalence of Human Papilloma Virus in Squamous Cell Carcinoma of Oral Tongue

Background and objective:  Oral tongue Squamous Cell carcinoma (SCC) commonly involves males between the sixth to eighth decades of life. Major risk factors are tobacco usage and alcohol consumption. The increasing number of patients developing oral tongue cancer without these well-known risk factors suggests that a viral infection, such as Human Papil...

The effect of pseudomonas exotoxin A on cytokine production in whole blood exposed to Pseudomonas aeruginosa.

To determine the effect of Pseudomonas aeruginosa exotoxin A (P-ExA) on cytokine production, we studied cytokine release induced by heat-killed P. aeruginosa (HKPA) in human whole blood in the presence or absence of P-ExA. P-ExA (0.01-1 microgram ml(-1)) caused a dose-dependent decrease in HKPA-induced production of tumor necrosis factor alpha (TNF), interleukin (IL-) 10, IL-6 and IL-8 (all P<0...
